Question

我遵循了https://pythonprogramming.net/how-to-embed-matplotlib-graph-tkinter-gui/的代码我只是用这种方式改变它，我有两个页面，每个页面都有一个画布。

我的问题是，当我初始化GUI时需要花费很多时间，看起来它在另一个页面冻结了几秒钟而不是起始页面“ChooseSensor”。

我会很高兴任何建议，我如何正确地初始化它。

这是我的代码：

import Tkinter as tk
import matplotlib
matplotlib.use("TkAgg")
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg
from matplotlib.figure import Figure
import matplotlib.animation as animation
from matplotlib import style 



#define LARGE_FONT
LARGE_FONT = ("Verdana", 12)
style.use('ggplot')

#define figures
#figure for canvas sensor1
f1 = Figure(figsize=(5,5), dpi = 100)
a1 = f1.add_subplot(111)

#figure for canvas sensor2
f2 = Figure(figsize=(5,5), dpi = 100)
a2 = f2.add_subplot(111)


class Sensors(tk.Tk):

    def __init__(self,*args, **kwargs ):
        tk.Tk.__init__(self,*args,**kwargs)
        container = tk.Frame(self)
        container.pack(side="top", fill = "both", expand = True)

        container.grid_rowconfigure(0, weight=1)
        container.grid_columnconfigure(0, weight=1)
        self.frames = {}

        for F in (ChooseSensor, Sensor1, Sensor2):   
            frame = F(container, self)
            self.frames[F] = frame
            frame.grid(row=0, column=0, sticky="nsew")
         self.show_frame(ChooseSensor)

    def show_frame(self, cont):
        frame = self.frames[cont]
        frame.tkraise()


class ChooseSensor(tk.Frame):

    def __init__(self, parent, controller):
        tk.Frame.__init__(self,parent)
        label = tk.Label(self, text = "Sensor Auswahl", font= LARGE_FONT)
        label.pack(pady=10, padx=10)

        button1 = tk.Button(self,text="Sensor 1",
                            command=lambda:controller.show_frame(Sensor1))
        button1.pack()

        button2 = tk.Button(self,text="Sensor 2",
                            command=lambda:controller.show_frame(Sensor2))
        button2.pack()


class Sensor1(tk.Frame):
    def __init__(self,parent,controller):
        tk.Frame.__init__(self,parent)
        label = tk.Label(self, text = "Sensor 1", font= LARGE_FONT)
        label.pack(pady=10, padx=10)
        button1 = tk.Button(self,text="back to home",
                         command=lambda:controller.show_frame(ChooseSensor))
        button1.pack()

        canvas = FigureCanvasTkAgg(f1, self)
        canvas.show()
        canvas.get_tk_widget().pack(side=tk.TOP, fill = tk.BOTH, expand = True)



class Sensor2(tk.Frame):
    def __init__(self,parent,controller):
        tk.Frame.__init__(self,parent)
        label = tk.Label(self, text = "Sensor 2", font= LARGE_FONT)
        label.pack(pady=10, padx=10)
        button1 = tk.Button(self,text="back to home",
                        command=lambda:controller.show_frame(ChooseSensor))
        button1.pack()

        canvas = FigureCanvasTkAgg(f2, self)
        canvas.show()
        canvas.get_tk_widget().pack(side=tk.TOP, fill = tk.BOTH, expand = True)



app = Sensors()
app.mainloop()

如何正确地在两个不同的tkinter gui框架中初始化两幅画布？
